Thomas Cooley is equally at home on opera, concert, and recital stages. His opera repertoire is extensive, ranging from Monteverdi and Handel, through Mozart and Rossini, to the present day. As a member of the ensemble at the Staatstheater am Gärtnerplatz in Munich, he sang such roles as Ferrando in Così fan tutte, Tamino in Die Zauberflöte, Belmonte in Die Entführung aus dem Serail, the title role in Idomeneo, and Count Almaviva in Rossini’s Il Barbiere di Siviglia. In May of 2010 he will appear as Bajazet in the Göttingen Handel Festival's new production of Tamerlano. As a concert performer, he has appeared throughout Europe and the U.S. with major orchestras and ensembles such as the Gewandhaus Orchestra Leipzig, Bavarian Radio Orchestra, Bach Collegium Stuttgart, Chicago Symphony Orchestra, Cleveland Orchestra, Minnesota Orchestra, Atlanta Symphony, and Orchestra of St. Luke’s. His concert repertoire encompasses over 400 years of music, including the works of Monteverdi, Bach, Handel, Haydn, Mozart, Beethoven, Mendelssohn, Elgar, Kodaly, Britten, and Penderecki.

Highlights of past seasons include his débuts with the Cleveland Orchestra under Franz Welser-Möst, the St. Louis Symphony with Nicholas McGegan, and at the Carmel Bach Festival under Bruno Weil, as well as return appearances with the Atlanta Symphony with Robert Spano, St. Paul Chamber Orchestra, Philharmonia Baroque Orchestra, Minnesota Orchestra, tours of Spain and Germany with the Windsbacher Knabenchor, the title role in a concert version of Bernstein’s Candide with the Charleston Symphony, and concerts with the International Bach-Academie Stuttgart, Bach's St. Matthew Passion in Carnegie Hall with Helmuth Rilling , as well as Beethoven’s Symphony No. 9 in Japan with Eiji Oue.

The art of the song recital is particularly important to Mr. Cooley, with recent highlights including his performance of Britten’s Winter Words and Still Falls the Rain at the Britten Festival in Aldeburgh, and Irish and Scottish folksongs of Haydn and Beethoven at the Göttingen Händelfestspiele. He performs regularly with the pianist Donald Sulzen in such works as Schubert’s Die Schöne Müllerin.

Recent CD recordings include Handel’s Athalia with Peter Neumann and the Kölner Kammerchor (MDG), the world premiere recording of Vivaldi’s Dixit Dominus for Deutsche Grammophon, and Handel’s Samson with the Festival Orchestra Gottingen/McGegan, released in 2009 on the Carus label.
